This series proposes to unduplicate the code used to find the member in an array closest to 'x'. The first patch adds a macro implementing the algorithm in two flavors - for arrays sorted in ascending and descending order. Other three patches replace duplicated code with calls to one of these macros in some hwmon drivers. v3: - don't add find_closest() to kernel.h - instead create a new include for helper macros - don't remove RANGE_TO_REG() and FREQ_TO_REG(), but replace their contents with find_closest() expansions - use kernel-docs to document new macros - rename find_closest_desc() to find_closest_descending() v2: https://lkml.org/lkml/2015/3/10/582 v1: https://lkml.org/lkml/2015/2/24/509 Bartosz Golaszewski (4): util_macros.h: add find_closest() macro hwmon: (ina2xx) replace ina226_avg_bits() with find_closest() hwmon: (lm85) use find_closest() in x_TO_REG() functions hwmon: (w83795) use find_closest_descending() in pwm_freq_to_reg() drivers/hwmon/ina2xx.c | 17 +++-------------- drivers/hwmon/lm85.c | 26 ++++++++------------------ drivers/hwmon/w83795.c | 8 +++----- include/linux/util_macros.h | 39 +++++++++++++++++++++++++++++++++++++++ 4 files changed, 53 insertions(+), 37 deletions(-) create mode 100644 include/linux/util_macros.h -- 2.1.4 _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
